2 Claims. (Cl. 161-1) This invention relates to means for mounting actor I! indicates generally a stove or range of electric clocks upon cooking stoves, ranges, or the any preferred construction illustrated as of the like and aims to provide a mounting from which electric type. The range in this instance is the clock may be readily detached and removed equipped at the rear with a mounting panel 5 when desired without disturbing the wiring. generally indicated by it whichlssupported upon Heretofore electric clocks on stoves and the like a bracket it within which the wiring connecting have received their source of current through the stove bus bars with the panel are concealed. wires extending outside of the range or stove, The panel itself consists of a plate ll of elecusually at the back thereof.

Referring'to the drawings more in detail, and t wi l be apparent. therefore. that the clock s particularly to Figs. 1 to 6 thereof, reference charmay be mounted on the panel by simply letting it down in proper position in which it becomes detachably locked by the tang 32. Whenthus positioned electrical contact is established through engagement of the various contact elements I! and 3| without the employment of exposed cords and without danger of the exertion of any strain upon the wiring within the clock case. Removal of the clock from the mounting for servicing or other purposes is readily effected by springing the upper edge of the back flange l8 rearwardly to disengage the tang 32, whereupon the clock may be lifted upwardly, as illustrated in dotted lines in Fig. 4, to free the case from the mounting and simultaneously break the electrical connections.

In the form of the invention disclosed in Figs. 7 to 11 inclusive, the design of the mounting is such that attachment of the clock to and detachment of the same from the mounting panel are accomplished by movement of the clock horizontally with respect to the panel instead of vertically, as in the form above described.

The clock in this instance is carried upon a support 35 projecting upwardly from the range II. The support is shaped to receive and sustain the weight of the clock case 31 and the mechanism therein, and carries in suitable position the mounting panel, indicated generally as 38. The panel in this instance comprises the plate 39 made of suitable insulating material and carries the three contact elements 4| fixed upon the free end of the leaf springs 42 which, in turn, are anchored by the bolts 43 extending through the plate 39 and clamped thereto by the nuts 44. Each bolt serves as a binding post for the electric wires 45 which are bound in place by the nuts 45. The plate 39, in this instance, is vertically disposed instead of horizontally, as in the form first described.

The wires 41 within the clock, one of which is shown in Fig. 11, are each attached to a post 48 carried by an insulated block 49 mounted in the rear wall of the clock case, and the outer end of each post terminates in a contact element 5i disposed in alignment with its companion contact element ll of the panel. Engagement of the various contact elements ll and 5| establishes the circuit for the clock mechanism.

In order to hold the clock case in assembled relation with the panel, an upwardly extending lip 52 of the panel frame 53 engages beneath one of the louvers 54 struck out from the back of the case. Cooperating with the lip 52 in retaining the clock and panel in assembled relation is a yielding hook-shaped lip 54' struck downwardly from the bottom wall 55 of the clock case, which lip telescopes over the rearwardly projecting bottom flange 56 of the panel frame and engages in an opening or slot 51 formed therein, all as illustrated in Figs. 10 and 11.

To detach the clock from the panel, an upward and outward pull is exerted upon the clock case which withdraws the louver 54 from the lip 52, whereupon the clock may be lowered to tree the lip 54' from the slot 51, thereby permitting the clock to be withdrawn horizontally, as indicated in dotted lines in Fig. 11.

In both iorms of my invention, the attachment of the clock to the panel serves to close the electric circuit, and the detachment of the clock breaks the circuit. In one instance the a'ttachment and detachment is effected by vertical movement of the clock, and in the other instance by horizontal movement. In both instances the clock may be readily mounted and dismounted without disturbing any of the wiring either within the clock case or that incorporated in the body of the range and connected with the binding posts projecting outwardly from the mounting panel.

While two forms of the invention have been disclosed, it is obvious that the structural details illustrated and described are capable of considerable modification and variation without depart ing from the essence of the invention as defined in the following claims:

I claim:

1. In a clock mounting, the combination of a panel adapted to be mounted upon a stove or the like and comprising a metallic frame provided at one edge with a projecting flange and having a block of insulating material mounted in the frame and provided on one face with a ptirality of depressions, contact elements mounted in said depressions so as to be exposed for engagement by companion contact elements, an electric clock provided with a plurality of contact elements exposed outside the case and arranged for engagement respectively with said panel contact elements, and cooperative means on the clock case and on said panel flange for detachably holding said case in predetermined position with respect to said panel so as to maintain contact between the contact elements carried by the case and said panel respectively.

2. In a clock mounting, the combination of a panel comprising a metal base having an outstanding flange and a block of insulating material secured to the base and provided on its exposed face with a plurality of depressions, contact elements mounted in said depressions, electrical connections extending from said contact elements through the base of said panel, an electric clock including a case and a plurality of contact elements carried by and disposed outside of said case in position to respectively engage the contact elements of said panel, and means carried by said panel flange for detachably locking said case in position on the panel so as to maintain contact between the contact elements carried respectively by the case and the panel block.
